Answer:

She spends 2 hours driving.

Step-by-step explanation:

The formula given is:

[tex]d = rt[/tex]

In which d is the distance traveled, r is the rate of speed, and t is the amount of time spent traveling.

Grace drives her truck a distance of 80 miles at a steady speed of 50 miles per hour.

This means that [tex]d = 80, r = 50[/tex]

To the nearest hour, how many hours does she spend driving?

We have to find t. So

[tex]d = rt[/tex]

[tex]50t = 80[/tex]

[tex]t = \frac{80}{50}[/tex]

[tex]t = 1.6[/tex]

Rounding to the nearest hour

She spends 2 hours driving.
